Comparing:
E951: Aspartame (Dipeptide Sweetener / 200x)
E968: Erythritol (Zero-Calorie Fermented Polyol)
E951 (Aspartame) is a methyl ester of the aspartic acid/phenylalanine dipeptide yielding ~200x the sweetness of sucrose. INS 951, ADI is 40 mg/kg bw/day, the historic sweetener in Diet Coke and tabletop sweetener packets.
E968 (Erythritol) is a four-carbon polyol produced by microbial fermentation of glucose by Moniliella pollinis. INS 968, ADI is Not Specified, delivering 70% the sweetness of sucrose with 0.0–0.2 kcal/g, zero GI, and 90% urinary excretion avoiding digestive distress.
